C, 60 hope this helps it helped me on my test
Probability that Eli will get a blue pen: 6 / 13 ( there are 6 blue pens and 13 pens together ).
Probability that Eli will not get the pink highlighter: 6 / 9 ( yellow + green = 4 + 2 = 6 and there are 9 together ).
P = 6/13 · 6/9 = 6/13 · 2/3 = 2/13 · 2 = 4/13 = 0.3077 = 30.77%.
Answer:
The probability is 4/13 or 30.77%.
Factor
(x+7)(x-2)
Proof
7-2=5
7*-2=-14
Zeros
x+7=0
x=-7
x-2=0
x=2
Final answer: C
In the spreadsheet, you get 1 for the mean and 0 for the MAD.
The mean of the dog washing time is 17, and the MAD is 5.5.
To find the mean, add all of the data points together and divide by 9, the number of data points:
15+20+10+18+25+10+12+30+13 = 153/9 = 17
To find the MAD, first find the difference between each data point and the mean; take the absolute value; then average these together.
|15-17|=2
|20-17|=3
|10-17|=7
|18-17|=1
|25-17|=8
|10-17|=7
|12-17|=5
|30-17|=13
|13-17|=4
2+3+7+1+8+7+5+13+4=50/9=5.5
The equation is 50+10x-10 which would simply to 40+10x and then change the x to 5 ( now it’s 5 times 10 ) changing 10x to 50 . 50+40 equals 90 . GOOD LUCK
